TOP OVEN-PLATE FOR COOKING-STOVES.

Specification of Letters Patent.

Patented Sept. 17, 1907.

To all whom it may concern:

Be it known that I, JAFEW S. VAN BUREN, a citizen of the United States,residing at Albany, in the county of Albany and State of New York, havein vented certain new and useful Improvements in Top Oven-Platesfor-.Gooking-Stoves; and I do hereby declarethe following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in cooking stoves and especially tothe construction of the top plates of the ovens thereof.

The object of the invention is to prevent bulging or cracking of saidtop oven plates and also to facilitate the circulation of the heated airand the products of combustion whereby all parts of the oven are evenlyheated.

The invention consists in the features of construc tion and combinationsof parts hereinafter described and specified in the claims.

In the accompanying drawings, illustrating the preferred embodiment ofmy invention, Figure 1 is a perspective view of a top oven plateembodying my invention. Fig. 2 is a vertical cross-sectional viewthereof taken through about the center of the bridge or arch. Fig. 3 isa longitudinal vertical sectional view taken centrally of said arch, andFig. 4 is a broken perspective view looking into the oven, the

circulation of the heated air being illustrated by the arrows therelative positions of the fire pot and smoke flue also being shown.

Referring more particularly to the drawings, 1 designates the top ovenplate which is formed of a single piece having a raised arch or bridge 2extending longitudinally and centrally thereof. Said arch increasesgradually in height from the end of the plate nearer the fire pot andits highest point is near the other end of said plate. From said highestpoint, the arch slopes abruptly to the level of the plate. In the upperportion of said abrupt slope is an opening 3 covered by a hood 4 securedto the arch and extending out nearly to the end of the plate.

By reference to Fig. 4 it will be seen that the highest portion of thearch or bridge extends up near to the top of the stove 'and thus servesto divide the products of combustion as they are discharged from thefire box and pass over the top of the oven, thereby The air passes outof this chamber through the opening 3 below the hood 2 which directs itdown the end flue, as shown by the arrows in Fig. 4. The provision ofthe arch as a part of the integral top oven plate pre vents said platefrom bulging or cracking by reason of any unusual expansion.

I claim:

1. In a cooking stove, the combination, with an oven, of a top plate forsaid. even having a longitudinal arch ex tending up near to the topplate of the stove and arranged between the vertical planes of the endsof said even, said arch gradually increasing in height in the directionof the rear end of the oven and constituting a division of the passagefor the products of combustion formed be tween said plates whereby saideven is evenly heated.

2. In a cooking stove, a top oven plate having an integral longitudinalarch extending up near to the top plate of the stove constituting adivision of the passage for the products of combustion formed betweensaid plates, said arch gradually increasing in height in the directionof the rear end of the oven and having means at its higher end forventilating said even.

' In a cooking stove, the combination, with the bottom, side and endwalls of the oven, and means to supply heated air to said oven, of thetop oven'plate having a longitudinal chambered arch provided with anopening in the rear end thereof, and a hood arranged over said openingand extending in the direction of the flow of the gases for the purposespecified.

4. In a cooking stove, the combination, with the bottom, side and endwalls of the oven, and means to supply heated air to said oven, of thetop oven plate having a longitudinal chambered arch which increases inheight from its end nearest the lire box to near the other end thereof,and thence sloping abruptly to the level of the plate, said archprovided with an opening near the top of said abrupt slope, and a hoodarranged over said opening and extend ing in the direction of the flowof the gases for the purpose specified.

In testimony whereof, I aflix my signature, in presence two witnesses.
